User Story

There is currently an increasing backlog of detect_intermittents and generate_perf_alerts tasks on SCl3 prod. (5000+ of the former, and 2000+ of the latter).
These tasks are run from the `bin/run_celery_worker` script:
https://github.com/mozilla/treeherder/blob/b040bb40455e2baac403813c882d143711262b49/bin/run_celery_worker#L18
Which is run on the treeherder-rabbitmq2.private.scl3.mozilla.com node.
However this node also runs:
bin/run_celerybeat
bin/run_celery_worker_hp
So between the above, the following queues are served by this single node:
default
cycle_data
calculate_durations
fetch_bugs
fetch_allthethings
generate_perf_alerts
detect_intermittents
classification_mirroring
publish_to_pulse
